With the rise of a new round of technological revolution and industrial transformation, intelligent manufacturing is becoming an important direction for global manufacturing reform and a commanding height for competing for competition. Major manufacturing countries have introduced relevant strategies and policies to promote smart manufacturing, and seize the high ground of a new round of industrial development. The advanced manufacturing industry is based on the manufacturing industry and the development of the service industry. It launches the "2017 Smart Manufacturing World Tour" series of articles to sort out and summarize the major issues of major smart manufacturing countries and regions in 2017. In the last issue, we learned about the progress of the United States in automatic/unmanned vehicles. In this issue, let us know about the progress of the United States in 3D printing .
Overall, in 2017, the United States made a lot of useful explorations in the development of 3D printing materials and new 3D printing technologies , and the results were impressive; while some additive manufacturing companies were trying new operating modes such as “3D printing farmsâ€; With the strong support of the US military, military 3D printing technology has developed rapidly.
In March 2017, Dartmouth College of the United States developed a super smart material with a cyclane compound and made it into a nano-sized polymer lattice cube using 3D printing, which became a 4D material, which can be lifted 15 times. For the object of its own weight, the application prospect is broad.
In June, the US Department of the Navy announced plans to use blockchains to control 3D printers. The blockchain enhances the ability to securely share data throughout the 3D printing manufacturing process, including design, prototyping, testing, production, final processing, and more.
In August, US robot manufacturer Slant Concepts split its 3D printing business into an independent company, Slant 3D. Slant Concepts hopes to use its custom-designed 3D printing farm to change the current state of 3D printing that is too expensive and too slow. In the future, Slant 3D plans to build a larger farm to reach a more competitive production scale than traditional manufacturing methods.
Also in August, the US Department of Defense Authorization Act (which includes provisions related to 3D printing) was approved by the US Congress, which requires the Secretary of Defense to submit its additive manufacturing program to the House Military Committee. The bill may benefit multiple additive manufacturing organizations and may be an important milestone in US military 3D printing.
In September, Brown University of the United States developed 3D printed biomaterials for on-demand degradation. This material can be used to fabricate complex microfluidic devices and dynamic cell cultures that are capable of degradation on demand and are associated with a particular chemical trigger. In addition, in the material development process, researchers also used stereolithography to make 3D printed structures.
Also in September, Idaho National Laboratory began using hybrid 3D printing technology to produce advanced nuclear fuel. The technology is said to improve the safety and efficiency of nuclear fuels and to handle any uranium-based materials that can be used for a variety of purposes.
In November, Lawrence Livermore National Laboratory made a new breakthrough in metal 3D printing - through cooperation with Georgia Tech, Oregon State University and Ames National Laboratory, 3D successfully played the common "marine level" Stainless steel 316L. This stainless steel has low carbon content, corrosion resistance and high ductility, and can be widely used in the manufacture of petroleum pipelines and engine parts. After testing, the researchers found that under certain conditions, 3D printed 316L products are three times more powerful and more ductile than traditionally made products.
In December, Oak Ridge National Laboratory created the world's smallest fine-tuning knob with 3D printing, with a width of only 100 microns. The world's largest fine-tuning knobs are also manufactured using additive manufacturing techniques. Scientists at Oak Ridge National Laboratory hope to demonstrate the potential of their 3D printing equipment.
In December, Lawrence Livermore National Laboratory and researchers at the University of California at Berkeley, the University of Rochester, and the Massachusetts Institute of Technology developed a technology to create complex 3D printed objects in seconds. This process is called "stereoscopic 3D printing" and overcomes many of the limitations of traditional additive manufacturing.
Overall, in 2017, the United States made a lot of useful explorations in the development of 3D printed materials and new 3D printing technologies, and the results were impressive; some additive manufacturing companies are trying new operational models such as “3D printing farmsâ€; With the strong support of the US military, military 3D printing technology has developed rapidly.
As the world's top science research university, MIT's smart manufacturing frontiers in 2017 are extremely rich, so the next issue will be a special article for MIT to end our trip to the United States.
